Please help Bear

Hi my name is Denise and am fundraising for Stephanie.Her story is that she rehomed two beautiful Maine Coons (brothers)through no fault of their own due to their circumstances suddenly changing.Despite having 4 cats of her own( one of which was another rehoming) she willing offered to take them.However one of them came with a illness which was never picked up previously (so insurance will not cover) that of severe jaundice and losing weight.After a hurried trip to the vets and having scans and biopsies(at an overall cost of £2500 which she managed to cover) it has been diagnosed the gallbladder needs removing.This is at a cost of up to £6000! Stephanie is out of her mind with worry as Bear is the sweetest boy you could wish to meet and deserves a chance to live.Not usually mine or Stephanies thing but am throwing this request out to kind hearted people to help where they can(every bit helps)Thank you kindly for listening and helping in advance
